This invention relates to, a device for in-` stallation in any air line between a reservoir and the tools or equipment supplied by the air line, which device is for the purpose of pre venting freezing of the fluid entrained in the air line in winter and for the dilution of any oils flowing throughthe line to the tools or equipment in the summer, which iuids by freezing, or oilsby drying, would endanger lo the operation of that equipment.

More specifically, this invention covers a vaporizer introduced into the air line of an` air brake systembetween the last main reservoir and-the service valves or equipment for the purposes noted above. Y

An additional object is to build a vaporizer of greater eiiiciency, accessibility, cheapness of construction and maintenance thanl has heretofore been used.

A further object is to build a simple vapor-V izer that will require little attention in operation.

Astill further object is to provide such a vaporizer that it will be necessary for the 'eicient use of only one of such articles on the whole train line. n Y

t Other and various objects will appear in` the detailed description ofthe speciiication.`

In the accompanying drawings, in which apreferred and modified construction of the invention is shown by way of illustration- Figure l is a the vaporizer; p

Figure 2 is an elevation, partly in section, showing the vaporizer assembled with. a centrifugal dirtcollector, the dirt collector not being a part of the invention; Figure 43 is a diagrammatic showing of the `vaporizer connected through the dirtA collector in the train line; and

Figure 4 is a modification showing another form of connection between the vaporizer and the train'line, in which the vaporizer is attached to an ordinary T ftting,in which case the wick carrying portion 2 ma be shortened so `as to Vaccommodate the 4 dimensions ofi the T. i i i. Referring particularly to Figure 3, the vaporizer indicated atA` is connected through the, centrifugal dirt collector B into the train cross sectional elevation of 1927. serir No. 192,466.` Y

. pipe line. In this embodiment ofthe invention, the dirt collectoris between the `last main reservoir C and the servicevalves, being connected to said reservoir by a pipe D and to said valves by pipes E connected through suitable couplings G. By the lastmain reiservoir` is meant that reservoir which is closest to the valves or equipment being supplied withair.` "i

Referring particularly to the vaporizer per se,'in the preferred form, 1 indicates the iuid container. Tapped, threaded or otherwise secured to said container is an extended neck, vapor fluid conducting holdngmeans, fluid conductor holding means, `or wick carrying o5 portion 2, said por-tion being shown asthreaded at 14 into said container. Wick or vapor fluid conducting means 3 extends throughu the neck 2 projecting part way-above said neck at 3 and down into the container as shown clearly in Figure 1. The neck is provided with a vent 5 for the purpose later tobe pointed out. The container proper isprovided with plugged tappedholest for lling, cleaningv or other purposes; Integral with 7 said containers 'are shoulders 15 provided for thepurpose of accommodating a`tool for tightly screwing or securing the vaporizer to the dirt collector or T. i The container is pro vided with threads 13 for engagement with corresponding threads 12 on the depending .chamber .or portion 11 of dirt collector B or common T H. The neck is provided with a guard, `or ypreferably a screenx, which is sweated on or otherwise secured to the wick carrying neck 2, at 6', for the purpose of preventing the wickfrom working upward* to block the air passage. r The operation of said device is as follows: Assuming that the vaporizer is installed in the airtrain line and is attached toa fitting or dirt collector in the air line, for winter use the container of the vaporizer is iilled with alcohol, which will saturate the wick,l and when the air enters the devicethroughport 7, 05 chamber 8, `penetrating to chamber 11, to passage 9 and out port 10, moving in the direction of the arrowK, it will absorb some of the alcohol and carry it through the whole air line, thereby preventing freezing. Air 10Q the reservoir because after atmospheric airk has been drawn into the compressor, compressed and discharged, it passes'through a set of cooling coils on its way to the reservoir, A

which removes the heat of compression'and reduces the temperature of the air, which results in the condensation lof themoisture which was intheairwhenit entered the compressor. This moisture entrapped inthe main'V reservoir'is of course drained as occasion requires. VVHowever, if the vaporizer were placed in the inlet to the compressor or on the discharge side .of the compressor, more alcohol would berequired to dilute the moisture in the air because it would have to dilute the moisture which is now entrapped in thereser- Voir. In the arrangementproposed, it has only to dilute the small amount of .moisture lnot removed from the air by the cooling coils. kiln-ordinary operation, there is no objection f to' freezing the water which accumulates in ytherein enters rthe the reservoir because locomotives are shopped frequently enough to be vdrained before accumulationiis suiiicient to flow outof'the outlet pipe. j f

Y From an-inspetcion of Figure 2, it will be `'observed that air having dirt in suspension centrifugal collector through the outwardly extending inlet tube ,7 and passes into the chamber 8 under a rapid swirling motion, with the result that the dust drops to the bottom of the chamber and the ycleansed* air passesoutwardly through t-he centrally arranged opening 9 and thence to the outlet pipe 10. .There are-many advan-u `tages to be gained from'combin'ing the dust collector `and the vvaporizerf in the manner herein disclosed, and although most of these will' be apparent several ofthem will be specificallymentioned herewith.

The swirling motion of the air results in a lthorough comingling betwen the vapor particles andthe air current as the latter passes upwardly through the tube 9, and the agitation of the air tends toy cleanse the surface ofV the screen a-s well as the exposed portion 3 of the wick. Furthermore, therapidly'moving air constantly carries away vapor "particles from thewick and prevents the exposed portion from becomingoversaturated andy clogged, it being appreciated, of.course,t hat wherethe end ofthe wickis exposed directly to thelowof air,dust`particles will collect on they wick and eventually. `clog' and otherwise impede the emission of vapor particles therefrom. The self-cleansingand thorough comingling features constitute important as-v pects of the invention which are not to be gained from a construction in which an eX- posed or screened wick is imposed in the path of an unagitated stream of air moving straight forward in the direction of the wick. Even if the wick is screened, a current of air directed straight against it will tend to clog the wick, and the collection of dust particles 'deposited thereon will eventually render the device inoperative.

7 It isA also-understood,-of course, that the disclosed vaporizer may be furnished as an attachment for introduction into systems that arev already in use without tearing down the system or otherwise putting it out of operation. Thus, the bottom of the'centrifugal dust collector-may be removed and the v'aporizer inserted inthe opening formerly occupied by the bottom section. `l'furthermore, the dust collector be vcleaned and the vaporizer `refilled merelyv by unscrewingV the vaporizer and removing vthe wick holding portion whereby two operation-s are combined into a single-operation, and the time generally eX- pended in cleaningthe. dust collector and re'- lillling the vaporizer is reduced by approxi- -matey one-half.

For summer use, the alcohol is .replaced lby benzine which whenacted on by the air, will penetrate the train line,- c'oat the inside of the pipes land so collect any dust particles which may be inthe compressed air, thereby keeping y the valves from becoming gummed.. It will,

of course, be understood that thewick carrying neck could be made integral with the receptacle portion of the device, but froman accessibilty point ofview, it is preferred to make the device in two part-s, this being more conductive to cleaning purposes, for the introduction of new wicks, etc.

It is to be understood that the modications shown are'merelyby way' of illustration and not limitation, as other and various forms of the device andits connectionsto ya fluid pressure air line will, of course, Aoccur to those skilled in the art. Y Y
